FOLDING STOOL.

Specification of Letters Patent. Patented Apr. 19, 1910.

Application filed November 10, 1909. Serial No. 527,329.

' tion indicated by 20 and receives the upper section indicated by 21.At the lower end of the intermediate section is a plug 22 which issecured in place in any suitable manner as by closing the metal of thetube into a groove 23 in the plug. The under side of the plug is prodried with a central hub or projection 2 1, for a purpose presently tobe explained. Near the upper end of the intermediate section is a crosspin which passes through opposite longitudinal slots 26 in the uppersection.

27 denotes transverse short slots which lead from the longitudinalslots. In the present instance I have shown three sets of thesetransverse slots, one set being at the top, one at the bottom and oneintermediate. These transverse slots provide three adjustments of heightfor the stool in use. The lower end of the lower section is preferablyclosed as by a cap 28. Near the upper end of the lower section arelongitudinal slots 29 which receive the upper ends of the legs. The legsare made of metal and of suitable size to be received within the uppersection. The upper ends of the legs are bent at an obtuse angle to themain portion thereof, as shown in Fig. 1.

In assembling, the intermediate tube is drawn out of the lower tube,then the angle ends of the legs, indicated specifically by 30, arepassed through the slots, and are To all whom it may concern:

Be it known that I, LEO J. OBnrnn, a citizen of the United States,residing at Ansonia, county of New Haven, State of Connecticut, haveinvented an Improvement in Folding Stools, of which the following is aspecification.

This invention has for its object to pro vide a folding or collapsiblestool which may be adjusted to different heights, will be simple andinexpensive to produce, easy to set up and take down and the seat ofwhich in the folded or collapsed position will receive the standard andlegs so that the stool may be conveniently carried under the arm as itweighs but little and occupies simply the space of the seat, which maybe made large or small as required and of any preferred configuration.The user is thus enabled to conveniently carry a stool with him for useat any open air gathering as a park concert or a political meeting.

With the above and other objects in view I have devised the novel stoolof which the following description in connection with the ac companyingdrawing is a specification, reference characters being used to indicatethe several parts.

Figure 1 is a longitudinal section of my novel stool complete in theassembled or set up position; Fig. 2 an elevation showing the stool inthe collapsed position, that is with the standard and legs socketed inthe seat as for carrying about; Fig. 3 an elevation of the upperscctionof the standard detached; Fig. at a section on the line 4. 1 inFig. 1 looking in the direction of the arrow; and Fig. 5 is a section onthe line 5-5 in Fig. 1 looking in the direction of the arrow.

lVly novel stool comprises a seat, a threesection telescopic standardand legs, in the present instance three.

denotes the seat, 11 the standard as a whole and 12 the legs. The seatis preferably of wood and is provided with a central socket 13 which ispreferably reinforced by a metallic cup-shaped bushing 14:, the bushingbeing provided with a flange 15 by which it is secured to the under sideof the seat as by screws 16. The seat is also provided on its under sidewith a groove 17 which partly receives the standard, a swiveled springclamp 18 securely retaining the standard in the groove, as clearly shownin Fig. 2. 1

19 denotes the intermediate section of the standard which slides withinthe lower secl wall of the section, the upper ends of the legs restingagainst the under side of the plug which is securely locked in place andtransmits the entire weight carried to the ends of the legs. It will benoted that the hub prevents the upper ends of the legs from movinginward, thus making the structure perfectly rigid in use. The uppersection is drawn out from the intermediate section, raised to therequired height and locked there by rotating the section slightly andplacing one of the sets of transverse slots in engagement with the crosspin, thus looking the standard at the desired adjustment. The seatissimply placed over the end of the upper section which is seated inbushing 14, the seat turning freely on the standard.

In disassembling, the seat is removed from the upper section, the crosspin disengaged from the transverse slots so that the section will slideinto the intermediate section, the legs are removed which permits theintermediate and upper sections to slide into the socketed between hub24: on plug 22 and the- I I I I I depending hub, one of said sectionsbeing constructed to extend below said plug and provided with slots atits upper end, and removable legs having ends constructed to passthrough said slots and between said hub and the wall of the slottedsection.

In testimony whereof I aflix my signature in presence of two witnesses.
